30:14-24 The desire, good in itself, but often too great and irregular, of being the mother of the promised Seed, with the honour of having many children, and the reproach of being barren, were causes of this unbecoming contest between the sisters. The truth appears to be, that they were influenced by the promises of God to Abraham; whose posterity were promised the richest blessings, and from whom the Messiah was to descend.
3-9. Bilhah … Zilpah—Following the example of Sarah with regard to Hagar, an example which is not seldom imitated still, she adopted the children of her maid. Leah took the same course. A bitter and intense rivalry existed between them, all the more from their close relationship as sisters; and although they occupied separate apartments, with their families, as is the uniform custom where a plurality of wives obtains, and the husband and father spends a day with each in regular succession, that did not allay their mutual jealousies. The evil lies in the system, which being a violation of God's original ordinance, cannot yield happiness.
